SOLDER MASK PER ANSI/IPC-SM-840

Electronics Forum | Fri May 27 12:34:20 EDT 2022 | SMTA-64387182

On my PCB fab drawings, I specify SOLDER MASK PER ANSI/IPC-SM-840, should I specify a CLASS rating? It appears at one time the CLASSES were 1, 2, or, 3. I believe, they are now T or H. Correct? Thanks, Joe

DAVE, Does this '7351 supercede the IPC-SM-782?(surface mount design and land pattern standard) how about IPC-CM-770? (guidelines for printed board component mounting) those are the two that I have? Russ

go to http:\www.ipc.org. get the following standards: IPC-A-600F Also look at the IPC-6010 series, this may help with your design group. Finally, consider getting IPC-SM-782 and IPC-7525. These are for Surface Mount Design & Land Pattern Standards
